我有一些代码，目前在活动上运行，我将它转换为使用一个主要活动和几个片段运行代替。我的一个活动在onCreate（）方法中运行GLSurfaceView。所以我修改这是onCreateView.The的问题是，虽然应用程序崩溃每当新片段尝试启动，我收到以下错误：Android的片段与GLSurfaceView
E/GLSurfaceView: eglCreateWindowSurface
java.lang.IllegalArgumentException: Make sure the SurfaceView or associated SurfaceHolder has a valid Surface
at com.google.android.gles_jni.EGLImpl._eglCreateWindowSurface(Native Method)
at com.google.android.gles_jni.EGLImpl.eglCreateWindowSurface(EGLImpl.java:90)
at android.opengl.GLSurfaceView$DefaultWindowSurfaceFactory.createWindowSurface(GLSurfaceView.java:808)
at android.opengl.GLSurfaceView$EglHelper.createSurface(GLSurfaceView.java:1077)
at android.opengl.GLSurfaceView$GLThread.guardedRun(GLSurfaceView.java:1471)
at android.opengl.GLSurfaceView$GLThread.run(GLSurfaceView.java:1240)
谁能给什么我做错了在转换提示碎片？
这里是我的主要活动推出的第一个片段：
//Start the fragment
Fragment gameManager = new GameManager();
fragmentManager.beginTransaction()
.add(R.id.fragment_container,gameManager)
.addToBackStack(null)
.commit();
下面是游戏管理相关的代码是一个片段： （1）空构造：
public GameManager(){
}
（2）onCreateView（）代码：
@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
fa = (FragmentActivity) super.getActivity();
CatAndroidApp app = (CatAndroidApp) getActivity().getApplicationContext();
RelativeLayout frame = new RelativeLayout(getActivity());
TextureManager texture = app.getTextureManagerInstance();
if (texture == null) {
texture = new TextureManager(getResources());
app.setTextureManagerInstance(texture);
}
//changed constructor
view = new GameView(this,getActivity());
renderer = new GameRenderer(view);
view.setRenderer(renderer);
view.requestFocus();
view.setLayoutParams(new LinearLayout.LayoutParams(LinearLayout.LayoutParams.MATCH_PARENT,
LinearLayout.LayoutParams.MATCH_PARENT, 1));
frame.addView(view);
boolean horizontal = getActivity().getResources().getDisplayMetrics().widthPixels < getActivity().getResources().getDisplayMetrics().heightPixels;
resources = new ResourceView(getActivity());
resources.setOrientation(horizontal ? LinearLayout.HORIZONTAL : LinearLayout.VERTICAL);
RelativeLayout.LayoutParams params;
if (horizontal)
params = new RelativeLayout.LayoutParams(LayoutParams.MATCH_PARENT, LayoutParams.WRAP_CONTENT);
else
params = new RelativeLayout.LayoutParams(LayoutParams.WRAP_CONTENT, LayoutParams.MATCH_PARENT);
params.addRule(horizontal ? RelativeLayout.ALIGN_PARENT_BOTTOM : RelativeLayout.ALIGN_PARENT_RIGHT, RelativeLayout.TRUE);
frame.addView(resources, params);
board = app.getBoardInstance();
turnHandler = new UpdateHandler();
return view;
}
最后，H ere是GameView的代码：
